The High Time Resolution Universe Pulsar Survey - II. Discovery of five millisecond pulsars by Bates, S., Bailes, M., Bhat, Ramesh, Burgay, M., Burke-Spolaor, S., D'Amico, N., Jameson, A., Johnston, S., Keith, M., Kramer, M., Levin, L., Lyne, A., Milia, S., Possenti, A., Stappers, B., van Straten, W.

“…These new discoveries occupy a short-period and high-dispersion measure (DM) region of parameter space, which we demonstrate is a direct consequence of the high time and frequency resolution of the HTRU survey. The large implied distances to our new discoveries make observation of their companions unlikely with both current optical telescopes and the Fermi Gamma-ray Space Telescope. …”
